Evansville, Indiana, sits on the Ohio River about 250 road miles from the Gulf. By boat, the trip is far longer—roughly 1,000 river miles—because you must follow the Ohio River to the Mississippi, then travel the Mississippi’s winding course to the Gulf.
At typical cruising speeds (8–12 mph), the voyage takes several days (often 4–7 days depending on stops, current, and vessel). Commercial towboats push barges the route regularly; recreational boaters should plan for fuel, provisions, lock passages, and variable river conditions.
